And Northumbrian Water have backed the club as sponsors with a £100 donation.

A total of 100 swimmers will each swim 50 metres freestyle in less than an hour under the eye of independent witnesses needed to prove to the Guinness Book of Record attempt is legitimate.

Club member Ollie King, 16, has welcomed the stars’ support.

“The fact that a television icon like Sir David Jason and James Corden have taken the trouble to back our world-record attempt is a real boost for everyone at the club,” said the Kings Priory School pupil.

“They have said good luck with the attempt and all the best which shows our bid for a place in the record books has clearly caught their imagination.

“I’m just hoping that getting backing from stars from television and the sporting world will focus everyone’s minds on Saturday and spur us all on.

“It will be a major achievement for the club if we can create our own little niche in the history books and I’m sure getting celebrity support on board will help us all on our big day.”

Club chairman Tracey Booth said the 100 swimmers – who range in age from nine to 48 – are geared up for their big day with a back-up team waiting in the wings if anyone has to drop out.

“We’re all totally committed to doing something special and all the swimmers are on a real mission to make history,” Tracey added.

“There’s a real team ethic at Tynemouth Amateur Swimming Club that we’re really proud of and everyone will pull together on Saturday to do their bit to make our world record dreams a reality.

“It would be a real feat for our members to get into the record books and a fantastic reward for their commitment and determination to keep pushing back the boundaries in the pool.”
